I only use sporter profile barrels in Bolt action.
I practice shooting 10 or 12 shots as fast as I can load for a reason, I don't want to miss the drive of my life because I cannot shoot quick, or stalk into a bunch of hinds and not maximise the stalk, why shoot one when 5 is better.
I use hot loads in the 243, normal loads in other guns and I'm yet to get a problem with throat erosion, its now getting to the point where I'm thinking that there is no such thing caused by shooting! it must be a cleaning issue or something else.
I have a cheep 243, bought for pest control and expected to replaces it when the barrel wore out one way or another, 30 years and many thousands of rounds and its as good as the day I bought it.
So Ill keep practicing because as I get older my reactions slow down anyway, so I need it.
